Ultra compact Palm-top DC Power Supply

  • Max Voltage: 8V to 36V
  • Max Current: 1A to 3A
  • Max Power: 24W to 36W
  • Ultra Slim

Palmtop size Variable DC Power Supply

R3K-36 series are ultra-compact, high-performance DC power supplies which achieve sufficient output of 36 W in the "palm-sized". This ultra-slim, (1.4 inches, 35 mm), supply, has the output voltage/current meter integrated as a standard feature.
This allows for simpler and easier operation.
The supply is very suitable for a multi-set and anti-sink current feature, to do QA or production testing.

Features and Benefits

We pursue usability!

  • Saving space by compact and light weight design
  • Suitable for research application by it's ultra low noise feature
  • Very quiet due to the adopting natural air-cooling system without cooling fan.
  • Output voltage and current meter are equipped standardly.
  • Output voltage and output current can be set speedily.


  1. The ripple is applied in the rated output from 10% to 100%.
  2. You can change the input voltage, and refer to options.
